CUTTER-HEAD.

SPECIFICATION forming part of Letters Patent No. 764,399, dated July 5, 1904.

.Application led October 8, 1906i. Serial No. 176,273. (No model.)

T @ZZ wir/mn it may concern:

Be it known that I, JOSEPH VILLIGER, Jr., a

citizen of the United States, residing' at Dixon, in the countyof Lee and State of Illinois,

have invented certain new and useful Improve? ments in Cutter-Heads; and I do declare the `following to be a full, clear, and exact de.

scription of the invention, such as will enablej` others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in may be easily and firmly attached to and removed from a shaft, quickly adjusted, and which will always run true.

A further object is to provide a cutter-head which will be simple and inexpensive in conl struction, strong, and well adapted to the use l for which it is designed.

With these and other objects in view the invention consists of certain novel features of construction, combination, and. arrangement of parts, as will be. more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a side view of the cutter-head arranged upon the end of a shaft. Fig. 2 is a cross-sectional view of the same on the line 2 2 of Fig. 1 looking in the direction of the arrow a. Fig. 3 is a longitudinal sectional view on the line 3 3 of Fig. 2 looking in the direction of the arrow. Fig. 4 is a cross-sectional view on the line 4 4 of Fig. 1 looking in the direction of the arrow Fig. 5 is a central longitudinal sectional view of a modiiied form of head.

Referring more particularly to the drawings, 1 denotes the cutter-head, which consists, preferably, of a cylindrical-shaped body having on its outer end anmannular recess 2, forming a seat for the cutter 3, which may be of any suitable design. A clamping ring or disk 4 has a centra-lly-disposed circular opening 5, around which on the inner side of the disk is arranged an annular shoulder o1' liange 6. Said disk is adapted to be clamped upon the outer face of the eutter-headby means of screws 7, which pass through the same and into said cutter-head, as shown, thereby holding the cutter 3 in place. To reverse the cutter, it is simply necessary to 4remove the disk 4 and turn said cutter around.

In order that the cutter-head, which is provided with a centrally-disposed longitudinal bore 8, may be readily attached to and removed frorn the operating-shaft A, a transversely-arranged slot 9 is formed in the side of the cutter-head near the outer end of the same, said slot extending to the center of or half-.way through lsaid head, as shown in Fig. 4 of the drawings.'

A radially-disposed longitudinal slot 1() is formed in the head between the slot 9 and the inner end Vof said head, said slot 1() extending' through the side of the eutter-head and communicating with the bore 8 of the same.

The arrangement of the slot 9 divides onehalf of the inner end of the cutter-head from the outer end, and the slot 10 cuts said inner divided portion into two parts, as clearly shown in Fig. 4.

In the side of the inner divided portion of the head above the slot 10 is formed a recess x 12, one wall of which is flat and arranged parallel with the walls of the slot 10. A hole 13 is formed in said flat wall to communicate with said slot 10 and is in alinement or coincident with a threaded hole 14, formed in thatl portion of the inner end of the cutter-head below the slot 10.`

A screw 15 is adapted to be passed through the hole 13 and screwed into the hole 14, the squared head of said screw engaging the flat wall of the recess 12. By turning' said screw in one direction the ends of the divided inner portion of the head above and below the slot 10 will be brought together, and the head thereby securely clamped upon the shaft. A reverse movement of the screw will permit said ends to spring' apart, thereby releasing the head and permitting the same to be removed from the shaft.

The bore 8 in the forwardu portion of the head, or that portion between the slot 9 and the outer end of the same, may be slightly larger in diameter than the inner or divided part of the head. The bore in the clampingdisk 4 may be slightly larger than the outer enlarged end or' the bore 8, as it is-not necessary that this enlarged portion of the bore 8 or the bore of the clamping-disk should engage the shaft A.

In Fig. 5 of the drawings is shown a modified form of cutter-head. In this instance an annular groove or channel 16 is formed in the outer periphery of the cutter-head, and in said channel is arranged a rubber ring 17. A head constructed in this manner is adapted to be used when steel feed-rolls are not employed on the machine.

A cutter-head having means for securing the same upon a shaft, as hereinbefore described, will always run true, whereas in the old method of attachment by means of a key and a set-screw impinging upon the shaft the cutter-head was frequently forced out of true when the screw was tightened.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A cutter-head having a transverse slot formed near the forward end and part way through the same, a radially-disposed longitudinal slot formed in the inner end of said head and communicating with said transverse slot, and means whereby said inner end may be clamped onto a shaft, substantially as described.

2. A cutter-head having a centrally-disposed longitudinal bore, a transverse slot formed near the outer end of and halfway through said head, a radially-disposed, longitudinal slot formed in the inner end of said head and communicating with said transverse slot and with said bore, and means for clamping the inner end of said head to a shaft, substantially as described.

3. A cutter-head having a centrally-disposed longitudinal bore, a transverse slot formed near the outer end of and half-way through said head, a radially-disposed, longitudinalslot formed in the inner end of said head and communicating with said transverse slot Vand with said bore, a clamping-screw arranged to engage the inner divided portions of the head, whereby the same may be removably secured upon an operating-shaft,sub stantially as described.

si.. A cutter-head carrying at its outer end a cutter, a clamping-ring arranged to secure said cutter on said head, a longitudinal bore formed in said head, a transverse slot formed near the outer end of and half-way through saidl head, a radially disposed longitudinal slot formed in the inner end of said head and communicating with said transverse slot and with said bore, a recess formed in the side of said inner end above said longitudinal slot, a screw arranged in said recess and adapted to connect the divided portion of said inner end and whereby the same may be clamped upon an operating-shaft, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
